Allow me to repost a page from mcs' board where jaan, a contract programmer for fasttrack, attempts an explanation. there are now about 4000 active supernodes at any one time:
Q. The supernodes don't cache search results at all? So is it cached at the client then? A. yes, the client caches the results for 10 seconds or so, just to protect the supernode. Q. You said something previously about using different branches of the network for repeated searches. A. well, they are not completely different. for example, the supernode you are connected to is always searched (because that's cheap). so are its neighbours, if i recall correctly. it's the third step that (effectively) searches a bunch of random supernodes on the net. however, as the third step is really expensive, it is performed only if the first steps yield less than N results, where N is about 10. in other words, the different branches only kick in if you search for really obscure stuff. Q. Is Morpheus simply remembering it once it found that this user had these files? A. yes, it's remembering the user/IP. so if the user did not have a static IP or was behind firewall, the chances of finding him are not so good. - js. "bunch of random supernodes" being the key here. i note that i was never able to find rare songs parked on my other computer in over a year of using napster without first using hotlist. |

Interesting discussion, Jack & Mike! Some comments...
Quote:
How many times I have heard comments like that of chickie-monkie's: "But I must say, I sooooooooooo miss the days of being able to use....Napster!" Yes, many people miss those days and for a good reason. The social tools of Napster together with its singular namespace were enough to provide the social thrill of being a permanent member in a global, never-sleeping online community that Napster grew to be. The post-Napster newbies may not even miss this experience as they have not known it... but they will come to know it, in time. Kazaa/Morpheus started out as a totally 'stuff-oriented' software in the spirit of Gnutella but the popular demand made FastTrack add browsing to it. As soon as you have browsing, the need for permanent (and working) hotlists becomes obvious. And so on... step by step the new generation of p2p is getting more social but it still hasn't reached the social intelligence level of the good old Napster. Quote:

How to proceed with the architecture? How to make the community of supernodes to work more efficiently so that searches can really reach the whole available content? One interesting way to enhance the search functionality would be to allow the supernodes and their 'clientele' to gradually self-organize into more content-conscious node clusters. For example, if you were regularly looking for reggae tunes, you would love to connect to a supernode hosting mostly reggae lovers. That way there would be much more relevant material available directly from your local neighborhood. And for the inevitable remote searches the supernodes could use their genre-awareness to form more effective links between each other. The next best targets for a locally failed reggae search would be other reggae-oriented supernodes etc. The idea is to allow the low-level nodes to 'migrate' between supernodes so that those with shared musical interests would get gradually closer and closer to each other. When you would join the network as a newbie, your searches would initially be 'blind shots' into your local supernode(s) and from there on to the wider supernode community. But should you repeatedly find something to download from a topologically distant supernode, this supernode could agree with your 'own' supernode to start hosting you so that you would be closer to people and content that you are interested in. - tg |

So how do you "hack" Morpheus so that you can download mp3s with higher bitrates than 128? I looked in my registry and didn't see a registry under Morpheus that said "bitrate limit." Can someone explain this to me? That damn bitrate limit is a real pain in the arse.

Thanks for the info mike and tg! Your procedure worked like a charm - I can't believe I missed that entry before! But one more question... Is there any way to put limitations on searches with Morpheus (e.g. only return matches with bitrate of 160 or higher)? That would be great!
Thank you. |

Instead of searching for 'Everything' search for 'Audio' and then choose 'More Search Options...' which opens up a list of extra limiters. Check the 'Quality' checkbox and you can set the bitrate limits for your searches. - tg |

I moved this thread over here as it contains good p2p-related information and discussion.

i debated putting it here to begin with tg but thought ultimately it was relevent for all the "napsterites". now that they've seen it in underground, p2p is fine. i am going to edit it somewhat and repost.
